Cervical lymphadenitis.

Case: An 18-month-old male infant originally presented with swelling in the right neck near the angle of the jaw which gradually developed over 4 to 5 days. He was fi rst taken to his primary care provider who noted multiple enlarged, nontender, submandibular lymph nodes and prescribed amoxicillin. However, because of increasing swelling after several days of antibiotic use, the patient was taken to the emergency department where he was prescribed, and completed, fi rst a 10-day course of amoxicillin/clavulanate, and subsequently, a 7-day course of azithromycin. The patient’s neck swelling failed to improve, though he never developed signifi cant fever or prominent tenderness.
